Precursors>Ancient Humanity (outsmarting the flood the way they did was pretty great)> Flood>Forerunners (I would say they beat humanity because the humans had just fought the flood and lost 1/3 of there population)>Covenant>or= to halo Humanity (well at the end they were pretty near to eachother but at the beginning definitely the Covenant) However the covenant did piggy back off the forerunners so Humanity>Forerunners in said: Onyx was made up of those bastards? Damn! My bad dawg. Precursors>Flood>Forerunner=Past Humans>Covenant>Halo CE Humans. However the flood are intelligent and would beat the necromorphs.Īctually they got lucky since the flood did not have enough high numbers and all of them were killed in a planet lvl explosion It took an engineer to kick the necro's ass. Flood are an inter galactic threat, it took weapons capable of killing all sentient life in the galaxy to defeat them.
